Santi Cazorla

Santi Cazorla was one of the big name signings that Wenger made in the summer of 2012, a summer in which he lost his talisman Robin van Persie to Manchester United. Cazorla didn’t take much time to adapt to life in England, scoring 12 goals and providing 14 assists in his first season at the North London club.
